問題文
An SRX Series Firewall pair inspects traffic between two Layer 2 segments of a plant network and runs in transparent mode today. The owner now wants stateful failover between two buildings and asks whether Multinode High Availability can be layered on top of the interfaces as they are. Which statement is correct?
選択肢
- Multinode High Availability supports transparent mode when both nodes are given the same grid identifier, because that identifier is what lets the pair present itself to the switches as a single Layer 2 forwarding domain.
- Multinode High Availability does not support high availability for transparent mode, so the inspected interfaces have to be moved to a routed or a default gateway design before this pair can be built.
- Multinode High Availability supports transparent mode once the interchassis link is bound to a Layer 3 interface, because only that link needs an address of its own while every inspected interface stays in transparent mode.
- Multinode High Availability supports transparent mode as long as both nodes run the same Junos OS version, because the state that the nodes exchange does not depend on the family that the inspected interfaces use.
